We crossed at Nogales and turned in our tip at km 21 midday on Monday. As of this morning no refund yet. In the past has shown up the next day as it is supposed to. Anyone else experience this?
You must turn in the permit and they remove the sticker - they scan everything and give you a receipt - you should get a refund in a couple days if you turned it in properly - and the guy entered everything properly - you should have paperwork to prove you turned it in - where you can go and what you can do to get a refund if it has not come through I do not know.
